Abstract (en)

The present invention relates to a braid-reinforced hollow fiber membrane. The hollow fiber membrane comprises a reinforcing material of a tubular braid and a polymer resinous thin film coated on the surface of the reinforcing material. The polymer resinous thin film has a skin layer with micro pores having a diameter in the range from 0.01 to 1 mu m and an inner layer of a sponge structure with micro pores having a diameter less than 10 mu m. Since the hollow fiber membrane of the present invention is coated with a polymer resinous thin film having a skin layer of a dense structure and an inner layer of a sponge structure with micro pores smaller than 10 mu m on the reinforcing material of tubular braid, the mechanical strength and the filtration reliability are excellent and simultaneously the water permeability is good.
